10 S&P 500 Stocks Just Made New 52-Week Highs
A small group of stocks reached new highs, with a heavy concentration in the technology space raising questions about valuation.
CrowdStrike (CRWD), with a market value of about $266.4 billion, is the largest company making a new high after gaining 37.7% over the last month. As of Wednesday, September 23, there are 10 S&P 500 stocks trading at their 52-week highs. The S&P 500 itself has returned +0.8% over the last month.
The list is concentrated, with the Information Technology sector accounting for 5 names and Health Care for 4 names. This raises the question of whether the business fundamentals for these technology names support their new price levels.

A new high is a question, not an answer.
Strength in a stock’s price can persist. But a 52-week high is simply a price, not a final verdict on a company’s value or future. The disciplined next step for an investor is to look past the price and check whether the business itself earns the level it has reached.
A new high tells you what the market already believes. The harder question is which of these runs management itself is underwriting. Our Guidance Momentum screen tracks exactly that: stocks where the company raised its own forward numbers.
One more pattern worth noticing: 5 of the 10 names are Information Technology stocks. When a whole group is making new highs together, a technology ETF like XLK, which holds 3 of these names, is one way to own part of the group’s strength without betting on which single name leads it from here.
Chasing Highs Is A Reflex. Owning Strength Is A System
A 52-week-high list is seductive: everything on it has been going right. But buying a stock because it is at its high is buying a price, and prices revert; what persists is the quality underneath the run.
The Trefis High Quality (HQ) Portfolio is built to own that quality before and after it makes headlines: roughly 30 businesses selected for consistent cash generation, strong margins, and resilient balance sheets, sized and rebalanced with rules. It has a track record of outpacing a benchmark that combines the S&P 500, the S&P MidCap 400, and the Russell 2000. Admire the list; own the system.
